Just as mine is confusing. My example was based upon 102,5Y 92,5M being 52.5y and 42.5m higher than 50y,50m, 0c. This would make the inverse (-52.5y and -42.5m from 50y, 50m) 0y, 10m, 2.5c not the number I quoted.
There is a reason I sport a fried egg.
I purposely left out the Cyan-Magenta-Yellow relationships to avoid confusion. Or, more truthfully, I left it up to someone else to take the bait. :rolleyes:

I rarely use - or need - cyan filtration. Somewhere around here I have some .jpg images downloaded from the "old" PC I just replaced, of a model illuminated with the light from color transparencies projected through a Hasselblad PCP80 projector, and photographed on Daylight CN. Light source ~ 3600K - but really not too relevant after passing through the tranny. Those prints *needed* an offsetting cyan filtration. When I find those files, I'll post a few in the "Technical Gallery".
